Invariant data-driven subgrid stress modeling on anisotropic grids for large eddy simulation

A Prakash, KE Jansen, JA Evans - Computer Methods in Applied …, 2024 - Elsevier
We present a new approach for constructing data-driven subgrid stress models for large
eddy simulation of turbulent flows using anisotropic grids. The key to our approach is a …
